INKVELL.

Application filed June 2E,

This invention relates to the construction of ink wells, of the fountain type and has for its object to provide an ink well of simple and inexpensive construction and which will nevertheles-s afford all the advantages of the more complicated and expensive ink wells now in general use.

A further object of the invention resides in the provision of an ink well of the fountain type which is so constructed as to permitthe same to be sealed by the application of an ordinary screw cap or the like, whereby thesame may be transported from place to place without danger of leakage.

ther objects and advantages of the invention'will be apparent from the following description when taken in connection with the accompanying drawing, in which: y

Figure l i-s al vertical section through the ink well with the cap applied; and

Figure 2 is a side elevation thereof with the cap removed.

Referring to the drawing in detail the numeral l indicates a bottle of any conventional shape and preferably formed of glass.

The bottle 1 may be of any of the well .known stock sizes now on the market and 1s con- .verted into a fountain ink well by the construction which will now be described.

Placed within the bottle l and resting on the bottom thereof is an inverted elastic cup 2 preferably of soft rubber. rfhis cup is provided with a cylindrical extension 3 formed integral therewith, and to this extension is anchored a tubular stem l formed of hard rubber, wood or metal, as preferred. It should be noted however, that the lower end of the stem 4 terminates flush with the inner wall of the cup 2 thereby avoiding any encroachment upon the capacity of the cup and furthermore avoiding any interference with the collapsing of the cup toward the bottom of the bottle.

The upper end of the tubular stem l terminates in a dared mouth 5 located within the neck of the bottle and held therein by means of a confining ring 6 which is preferably secured to the mouth of the bottle by a compression fit. This ring 6 is provided with an overhanging ange 7 which is in direct engagement with the upper edge of the mouth portion 5 of the tubular stem.

|lhe neck of the bottle l may be provided with threads 8 or other fastening means for a cap 9 which serves to close the bottle, and

it should be here noted that the cap when in sealing position is in engagement with the mouth 5 of the tubular stem as well as with the flange thereby completely sealing the ink well against leakage. In the present instance the cap 9 is provided with a depressed portion l0 to allow contact of the cap with the flared mouth 5.

In assembling the device the fountain con struction, which has been previously formed by uniting the members 2 and 4L, is inserted within the bottle, which is filled with ink in the usual manner. The confining ring 6 is then compressed onto the neckof the bottle and through the medium of its flange 7 functions to hold the parts in their operative position. The cap 9 is then applied to the botn 'fle and especially through its contact with the. mouth 5 serves to seal the ink well against leakage during shipment or other transportation thereof. v

fn operation, the caprS) being removed, the pen is dipped into the well cavity or mouth 5 and pushed slightly downwardly; this causes the soft rubbery cup 2 to collapse to a greater or less extent thereby reducing the internal capacity of the cup and causing t-he ink within the cup to be forced upwardly` within the tubular stem t and mouth 5 and into contact with the pen. This downward pressure upon the cup 2 also causes its lower edge to form a seal between itself and the bottom of the bottle thereby preventing the escape of ink within the cup. When the pressure is removed from the fountain structure by withdrawal of the pen the elasticity of the cup serves to return it to normal shape and consequently the mouth 5 to its position of engagement with the flange 7 In this phase of the operation of the fountain. device the ink in the tubular stem is caused to recede, but a certain amount of seepage from the bottle to the interior of the cup 2 is created by suction within the cup and the atmospheric pressure on the surface of the ink in the bottle thereby forcing ink from the bottle to the interior of the cup. These several Aactions are caused by the inverted elastic cup 2 which also functions to hold the mouth portion 5 of the tubular stem normally in engagement with the flange 7 of the confining ring 6.

From the foregoing description when considered in connection with the accompanying drawings it will be observed that I have devised a very simple and inexpensive fountain ink well which comprises merely a conventional bottle, a cover therefor, and a simple fountain device; that the device is readily and quickly assembled; is highly efcient in operation; and is easily converted from a fountain ink well to a transportable leak-proof bottle by the mere application of a cap.

In accordance with the patent statutes I have described what I now believe to be the best embodiment of the invention, but it is to be understood that many changes as to details may be made without departingl from the spirit of the invention, andv all' such I aim to include within the scope of the appended claims.

Vhat I claim as new and desire to secure by Letters -atent is:

l. A fountain ink well inciuding a bottle, said bottle being of conventional type, a fountain construction confined within the conventional bottle, threads on the neck of said bottle, and a conventional cap adapted to be screwed thereon into cooperative sealing relation with said fountain construction.

2. A fountain ink well including` a conventional bottle, a fountain construction including` an inverted elastic cup normally resting on the bottom of said bottle, a tubular stem secured to and in communication with said cup, said stem having a flared mouth terminating substantially iiush with the mouth of the bottle, a confining` ring mounted on the neck of the bottle and having an annular flange projecting over the flared mouth of the stem, threads on the inzette? bottle neck below said confining ring, and a cap adapted to be threaded thereon into cooperative sealing relation with the flared mouth of the fountain construction.

A fountain ink well including a conventional bottle, a fountain construction within the bottle, a ring mounted 0n the neck of the bottle for confining the fountain construction, and a cap screwed on said bottle into cooperative sealing relation with respect to the ring and fountain construc tion. e

et. A fountain ink well including a conventional bottle, a fountain construction within the bottle, means for confining the fountain construction, a cap adapted to be threaded on the bottle, and said caphaving a downwardly dished portion cooperating with the fountain construction to effect a seal.

5.' A fountain ink well including a conventional bottle, a fountain construct-ion within the bottle, said fountain construction comprising an inverted elastic cup resting on the bottom of said bottle and of substantially the same diameter as the interior diameter of the bottle body, a tubular stem secured to and in communication with said cup, said stem having' a flared mouth of substantialiy the same diameter as the interior diameter of the bottle neck, said fiared mouth terminating Vflush with the mouth of the bottle, a confining ring mounted on the bottle neck and having an annular flange projecting over the flared mouth of the stem, and a cap adapted to be secured on said bottle in cooperative sealing relation with the fountain construction.
